3LW's Kiely Williams and Adrienne Bailon are coming out of their recent lineup squabble with a roar.

After A Girl Can Mack is released on October 22, the singers have agreed to make their film debuts in an adaptation of Deborah Gregory's "Cheetah Girls" book series.

Williams and Bailon, who vowed to continue on with 3LW after Naturi Naughton's controversial departure in August (see "3LW Become 2LW: Naturi Says She's Out Of Group"), will play two of the members of the multiracial teenage singing group the book series is centered on, according to their spokesperson.

Child actor Raven Symone ("The Cosby Show," "Dr. Dolittle"), who has also released two hip-hop albums, has been cast as a group member as well.
